[solved] Inscrutable bug in python fuse code?

I have a bug in my FUSE operations code that I can't figure out.  I'm using the ctypes fusepy wrapper with Python 3.  I'm not really familiar with fuse or ctypes, though I did my best to try to figure out what's going on, so I hope someone here could help me out.

I think the problem is that getattr is not being handled properly.  After trying to mount fuse and doing a ls on it, it says input/output error.

Here's my code: https://github.com/darkfeline/dantalian  The fuse operations are here: https://github.com/darkfeline/dantalian … n/mount.py  The library I'm using is here: https://github.com/darkfeline/dantalian … an/fuse.py

Here's the output from the logging mix-in:

2013-02-07 23:13:27,941 DEBUG @fuse.log-mixin -> getattr / (None,)
2013-02-07 23:13:27,943 DEBUG @fuse.log-mixin <- getattr {'st_mtime': 1360296806.2537441, 'st_size': 4096, 'st_atime': 1360296806.2537441, 'st_gid': 1003, 'st_uid': 1000, 'st_mode': 448, 'st_ctime': 1360296806.2537441, 'st_nlink': 4}

The debugging output from fuse:

FUSE library version: 2.9.2
nullpath_ok: 0
nopath: 0
utime_omit_ok: 0

If any other info would be helpful, I'll add it.

Re: [solved] Inscrutable bug in python fuse code?

I figured out the problem, my mode bits didn't have file or directory set, so understandable it wouldn't work.
